First reported by The Miami Herald, Tannehill was placed on Injured Reserve Saturday morning after it was confirmed he would undergo reconstructive surgery on a partially torn ACL. The team also confirmed the news via Twitter, while announcing they signed a new player.

We have signed linebacker Junior Sylvestre and placed quarterback Ryan Tannehill on injured reserve.

Tannehill originally injured his knee late last season. He was sidelined him for the final three games of the season, and missed a playoff matchup against the Pittsburgh Steelers. Then, on Aug 3. he re-injured the knee on a non-contact play during training camp.

Miami quickly signed former Chicago Bears QB Jay Cutler after Tannehill’s latest injury. Cutler agreed to a one-year deal worth $10 million. Dolphins head coach Adam Gase played a huge role in getting Cutler to Miami. The two previously spent some time together in Chicago back in 2015 when Cutler was the starting QB and Gase was the offensive coordinator.
